Overview of Q3D State Space Coupling

Note:

The Q3D State Space component creates a state-space model that is valid over a range of frequencies, while the Q3D Equivalent Circuit component creates an equivalent circuit at a single frequency.

To prepare and use a Q3D State Space component, do the following:

  1. Create a 2D or 3D model of the device in Q3D.
    Note:

    Avoid using illegal characters such as the “space” character in design names. Illegal characters are replaced with an underscore character. See Names of Components and Variables for additional information.

  2. Perform a frequency sweep electromagnetic field solution.
  3. In Twin Builder, add the Q3D state space coupling component to the sheet.
  4. Create the rest of the simulation design on the sheet.
  5. Start the simulations in Twin Builder.
    Note:

    To make changes in the coupling component, you must edit the Q3D design, recalculate the field solution, and re-export the model.
